Two vulnerabilities have been discovered in the libtiff library and the
included tools, which may result in denial of service or the execution
of arbitrary code if malformed image files are processed.


For Debian 9 stretch, these problems have been fixed in version

We recommend that you upgrade your tiff packages.
